System Configuration and Operation Reinitializing the System
When you remove and replace most card types, the NVRAM remembers the old card’s
settings. If the same kind of new card is inserted in the slot, you do not need to reprogram the
settings. However, if you replace a card with a different type of card, the system lets you delete
the old card, so that you can program new parameter settings for the new card (see the
Accept
function described earlier in this chapter).
When you remove and replace an Interface card, the system automatically resets itself. If the
new Interface card was not previously used, you must re-register the system. If the new
Interface card was previously used, either it will use its internal settings, or the system will
request that you “zip” it, causing it to be reprogrammed.
When you remove and replace a CPU card with an
identical
CPU card, the system
re-evaluates the Interface card’s NVRAM and writes the old parameters (including your
current passwords) to the new CPU card. Your CPU card is labeled CPU-3 on its faceplate
ejector.
If the CPU card is replaced with an identical CPU card but the new card has a different
firmware version, a “zip” must be performed.
